TONIGHT’S MUST-SEE: “The Good Wife” finale, 9 p.m., CBS. Some people assume that all praise-worthy, award-worthy dramas are on cable. “Good Wife,” however, has been a splendid exception. In seven years, it’s drawn 39 Emmy nominations, winning for star Julianna Margulies (twice) and for other actresses (three times).

Now the finale starts in mid-crisis. Last week, Peter decided to accept a plea bargain ... but too late; the jury was already returning. What’s the verdict? Will Alicia leave Peter now for her company’s detective? Will her new firm survive turmoil? We may see, as an excellent show says farewell.

The result is a good mystery (as usual), with wonderfully underplayed work by its star, Kenneth Branagh. It’s also the beginning of the end: Wallander will be back in Sweden on the next two Sundays, as a great, 12-movie series reaches its emotional conclusion.

TONIGHT’S ALTERNATIVE: “The Story of God” conclusion, 9 p.m., National Geographic. In this sprawling series, Morgan Freeman has spanned the globe to see how religions answer the great questions. Now he ends with a big one: Are there miracles, or just stunning coincidences?

Freeman starts and ends with amazing survivors: One, a widow-washer, fell 47 floors; another had cancer so extreme that he was given only months to live. The latter — almost two decades later — calls it a miracle; the former doesn’t: Why would God miraculously save him and not his brother, who fell with him? Such questions are part of an eternal dialog ... and Freeman is ideal to lead it.

Other choices include:

“Talladega Nights” (2006), 6:30 p.m., and “American Speed: The True Story of NASCAR,” 9 and 11 p.m., CMT. First is some amiable silliness, with Will Ferrell as a champion driver; then is a new documentary, viewing how NASCAR began and grew into a mammoth force.

“Madam Secretary” season-finale, 8 p.m., CBS. After surviving last week’s terrorist-hunting ordeal, Henry (Tim Daly) is ready for ordinary life again. He makes waffles, organizes mini-golf ... and finds himself in the midst of crucial family moments. At times, this is a surprisingly light hour, complete with a great scene for a speech-writer. But at the core are fresh crises for Henry’s wife (Tea Leoni), the secretary of state. The result mixes humor, emotion and a big change for next season.

“Little Big Shots,” 8 p.m., NBC. This blossomed quickly into a surprise ratings hit, so NBC wants to extend the season. Tonight, it shows top-10 moments from the first eight episodes.

“The Family,” 9 p.m., ABC. This tangled drama reaches a key point: It’s election day for Claire, who continued her run after learning (and keeping secret) that the return of her son Adam was a ruse by her daughter Bella. “Adam” is actually Ben; tonight, he and Bella both spill secrets. Also, Nina tries to get a confession from Doug ... unaware that his loved one, Jane, has FBI agent Clements captive.

“Last Man on Earth,” 9:30 p.m., Fox. After some funny moments early, this suddenly reminds us of the basics: This is, after all, a show about the few survivors of a global virus. It’s a tough transition.

“Quantico,” 10 p.m., ABC. A week before the season-finale, it’s time for these people to graduate and become FBI agents. Flashing forward, Alex learns that one of her classmates was deceitful.

“Elementary” season-finale, 10 p.m., CBS. Sherlock learns that a global crime organization was at the heart of the murder attempt on his father. The effort to fight back is hampered by father-son issues.
